i woke up this past saturday, 2 days ago, with a pain in my upper inner thigh. it does not go away, it hurts most when walking on that leg, using the leg while driving. the pain feels in one spot, but goes down like in a line down to the knee where it hurts to the touch (the line, not the knee). i do not see any redness or swelling, just the pain. i feel very little pain in the calf on same leg. i am 12 weeks pregnant
